海水
How to Understand
海水 (hǎi shuǐ) literally means 'sea water' and refers to the saltwater found in oceans and seas. It is distinct from freshwater, which is found in rivers, lakes, and other inland bodies of water.
The character 海 (hǎi) means 'sea' and comes from ancient Chinese characters that depicted a vast body of water. 水 (shuǐ) means 'water,' one of the most common and fundamental characters in Chinese. Together, they form a compound noun describing the specific type of water found in marine environments.
海水 is commonly used in scientific, environmental, and everyday contexts. For example, it is used when discussing oceanography, marine life, or coastal activities. In cultural terms, the sea holds symbolic meanings in Chinese poetry and philosophy, often representing vastness, mystery, or the unknown.
